Final Effluent Limitations Guidelines and Standards for the 
Coastal Subcategory of the Oil and Gas Extraction Point Source 
Category; Correction

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: EPA is correcting minor errors in the preamble and effluent 
limitations guidelines and standards for the coastal subcategory of the 
oil and gas extraction point source category, which appeared in the 
Federal Register on December 16, 1996 (61 FR 66086).

EFFECTIVE DATE: these corrections shall become effective January 15, 
1997, except for Sec. 435.45 (NSPS), which becomes effective January 
13, 1997.

FOR FURTHER INFORMATION CONTACT: Charles E. White, Office of Water, 
Engineering and Analysis Division (4303), U.S. Environmental Protection 
Agency, 401 M Street, SW, Washington, DC, 20460, (202) 260-5411, 
[email protected].

SUPPLEMENTARY INFORMATION: In a final rule published December 16, 1996 
(61 FR 66086), EPA established final effluent limitations guidelines 
and standards for the control of wastewater pollutants. The final rule 
contained some minor errors that are discussed briefly below and are 
corrected by this document. The effective dates and date of issuance 
for purposes of judicial review are stated in the December 16, 1996 
final rule.
    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
action is not a ``significant regulatory action'' and, is therefore not 
subject to review by the Office of Management and Budget. In addition, 
this action does not impose any enforceable duty or contain any 
unfunded mandate as described in the Unfunded Mandates Reform Act of 
1995 (Pub. L. 104-4), or require prior consultation with State 
officials as specified by Executive Order 12875 (58 FR 58093, October 
28, 1993), or involve special consideration of environmental justice 
related issuess as required by Executive Order 12898 (59 FR 7629, 
February 16, 1994).
    Because this action is not subject to notice-and-comment 
requirements under the Administrative Procedure Act or any other 
statute, it is not subject to the provisions of the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.).
    Under 5 U.S.C. 801(a)(1)(A) as added by the Small Business 
Regulatory Enforcement Fairness Act of 1996, EPA submitted a report 
containing this rule and other required information to the U.S. Senate, 
the U.S. House of Representatives and the Comptroller General of the 
General Accounting Office prior to publication of this rule in today's 
Federal Register. This rule is not a ``major rule'' as defined by 5 
U.S.C. 804(2).
